I am using OS X 10.9.1 (Mavericks).
What are the systematic steps to install to Gvim or MacVim in Mac OS? If you write the steps using 1, 2, 3, ..., it would be easy
That Macvim is obsolete. Use https://github.com/macvim-dev/macvim instead
See the FAQ (https://github.com/b4winckler/macvim/wiki/FAQ#how-can-i-open-files-from-terminal) for how to install the mvim script for launching from the command line
export PATH=/usr/local/bin:$PATHbrew updatebrew install vim && brew install macvimbrew link macvimYou now have the latest versions of vim and macvim managed by brew. Run brew update && brew upgrade every once in a while to upgrade them.
This includes the installation of the CLI mvim and the mac application (which both point to the same thing).
I use this setup and it works like a charm. Brew even takes care of installing vim with the preferable options.
Download the latest build from https://github.com/macvim-dev/macvim/releases
Expand the archive.
Put MacVim.app into /Applications/.
Done.
There is also a new option now in http://vimr.org/, which looks quite promising.
